Excellent! I was looking for nonuniform FFT as a component for the interpolation. I am thinking of combining nufft with czt (from scipy) for the interpolation.

Interpolation by the sinc function is equivalent to what yiu get if you'll synthesize a smooth function by summing its Fourier component obtained via FFT of the data.
